It's true that inertia is the same and you'd land with the same force, if anything perhaps slightly slower as there'd be more distance for air friction to slow you down. Presumably the dangers of a botched landing would be roughly equivalent to the Earthly dangers, though again if anything it'd be slightly safer as you'd have more time to react during flight time to minimize those risks that might arise from a botched start.

So, if anything the odds of breaking your head or neck would be somewhat less than when doing the equivalent sport on Earth... and here such things are quite rare in sport.
